States, residing at Chicago, in the county of},

5 Cook and State of lllinois, have invented ai certain .new and usefulImprovement in; -Window-Sashes, of which the following is aspecification. f Y Our invention relates to windows, andhas for its object'to'provide certain new and use-, ful im rovements hereinafter morefully de-l scribed t Figure 1 is a-front elevation of a window-containing our invention with parts illus-' Fig. 2 is a verticalsection. Fig. 3 is a cross-section on the line 33 ofv Figs. land 6. Fig.4 is a cross-section of the latchnot 'in use. Fig. 5 is a verticalsection on the line 5 5, ofFig. 3. Fig. 6 is a vertical section on theline 6 60f Fi 4.. Fig.

. 7 is a detail of the pulley-and-weig t device, and Fig. 8 is a detailof the pulley. Like parts are indicated by the same letter in all thefigures. r p

A A are the parts ofthe window-casing, of any desired size and form,associated with the window-casing portions B B, the whole adapted toform a window frame or casing of substantially the ordinary form'andstyle.

, To work out our invention satisfactorily, the

. u per window-sash should be shorter than t elower. This may beaccomplished in some cases by putting the extension-piece I C intheupper frame.

D is the u per window and sash. D D are hinges W ereby this uplperwindow-sash is hinged to a iece which s 'des in the hollow .verticalpiece, T", which is slotted at D? and associated with the parting-railiece-D owj and sas ,provided with the hinges E E, whereby it is hinged.to a vertically-sliding iece E provided with an upper hook E an a neckE and an inner enlargement. E adapted totravel in the hollow verticalpiece E. E E are rollerbearin s which are arranged in this hollowVertical-v piece on both sides of the 'neckZand enlargement E and E sothat the hinged piece freely travel vertically without One end of thiscordor chain travels about 1 a the pulley F on the case F which is at-.ing 'vertica sliding piece, to which is hinged the upper window. Theattachment of the chain or cord to the vertical piece upon can be movedup or down and both are held hinged is I bindingor cramping. The hinge Dis in like manner associated with a like art which travels in a verticalhollow iece F is a-weight suspended om the pulleyF', around whichtravels the cord or chain F tached to the window-casing, and the otherend of thecord or chain F travels over the pulley F which is attached tothe frame F, which is in turn secured to the wood casing. The extremityof one end of the cord or chain is attached to the hook E, as shown inFig. 1,

and the other extremity of the cord or chain to a corres ondinghook onthe correspondwhich the upper sash is hinged 1s precisely the same asin' the case of the lower sash, as shown in Fig. 1. Thus either of thewindows in their predeterminedpositions by the action of one and thesame weight. The ulley maybe of a special pattern, whichwe w' nowdescribe. It may consist of a central block Gr, attached to its case ina fixed position by means of the rivets G G and rovided with an outerrotating frictional rIm G which may be grooved, as at G and in whichtravels the cord F or it may be provided with a sprocket for a chain, ifdesired. Thus, as previously suggested, either of the windows can bemoved up or down to any desired extent. The side of the window-casingopposite the side where the windows are rovided with laterally-movableparts, whic we will now describe.

Referring to Fig. 4, the lower window will travel in the groove J,formed between the pieces J and J which are su ported on the back plateJ This back late J is connected to the fixed ortion o the casing B bythe pivoted links 4 J each of which is pivoted at its upper end to theprojection J on the-back plate J and at'its lower end to a 'swunginwardly, as indicated in Fig. 3.

inwardly. Inorder to move these parts J and J backwardly, however, thewindow 7 must be first raised until the latch is uncovered. The latchconsists of the part M, having the inner hook M and associated with theguidelates M M one on each side of the plate the slot M so that it canbe raised. N is a fixed block on the partB, provided with a{ hook N. Byraising the latchiece M in its slot and then pushing it, toget er withthe. parts J and J inwardly the latch M will engage the hook N and theparts will be locked in the position indicated in Fig. 5. The lower sashmay now be moved down anId t may then be washed. It can also be runupwardly out d the way, and the upper sash can be lowered and also swunginwardl In a case where the sashes are of such ength and so mounted thatthe u per sash cannot be drawn down below the l dwer edge of the raisedlower sash then the up er sash can, nevertheless, be swung inward yuntil it engages the lower ortion of the raised lower sash, and this wilgive suflicient opportunity for washing it, &c.

O is a trough-like sheet-metal plate with the corner-ribs O, and itserves to support the non-moving parts.

Of course these parts may be greatly altered, and we do not wish to beunderstood as giving exact proportions or relations of construction. Theparts may be greatly modified in their several relations, form, size,and proportion.

The use and operation of our invention are as follows: When the windowis closed, the parts are in the positions indicated in Fig. 1. Obviouslyeither the upper or the lower sash can be moved up or down to anydesired position, the single weight controlling both.

' When the person in charge desires to clean the windows, he will raisethe lower window until the latch is exposed. He will then push the latchup and push it, with the strips J and J and their associated parts, intothe osition shown in Fig. 3, whereupon the atch will engage the hook Nand the parts will belocked in this position. The upper sash can now belowered and swung into the room, as indicated in Fig. 3, for cleaning,

The part M passes through painting, or repairing, as the case may be.The sash can then be pushed upwardly while in its inwardly-swungposition andthe upper sash can be moved downwardly until it is below thelower sash.

We claim 1. In a window, the combination of a window-sash with avertically-movable piece on which it is hinged and antifriction-ballsbetween the vertically-movable part andthe piece in which it moves suchsash grooved so as to inclose the vertical movable piece.

2. In a window, the combination of a hollow vertical piece with avertically-movable part, and a window-sash hingedto saidvertically-movable part, and antifriction-balls in the hollow part suchsash grooved so as to inclose the vertical movable piece.

3. In a window, the combination of a 1101- low vertical piece with aslot in one side, a vertically-movable portion having a narrow neck topass through the slot, and a larger portion to lie in the hollow, and awindow hinged to the vertically-movable portion, and antifrictionalballs in the hollow of the vertical part such sash grooved so as toinclose the vertical movable piece.

4. In a window, the combination of a window-frame with aninwardly-moving side section which permits the window-sash to swinginwardly at such side, said inwardly- -moving portion supported onpivoted links secured to a stationary part of the windowframe and alatch device to hold the side section to the window-frame.

5. In a window, the combination of a window-frame with aninwardly-moving side section which permits the window-sash toswing'inwardly at such side, saidinwardlymoving portion supported onangularlyplaced pivoted links secured to a stationary part of thewindow-frame and a latch device to hold the side section to thewindow-frame.
